COOKING-STOVE.

SPECIFICATION forming part of Letters Patent No. 596,710, dated January4, 1898.

Application filed July 9, 1896. Serial No. 598,604. (No model.)

To all whom, it may concern:

Beit known that I THOMAS E. KENNEDY, of Rochester, in the county ofMonroe and State of New York, have invented certain new and usefulImprovements in Cooking-Stoves; and I do hereby declare the following tobe a full, clear, and exact description of the same, reference being hadto the accompanying drawings, forming a part of this specification, andto the reference-letters marked thereon.

My present invention relates to stoves and ranges, and has for itsobject to improve the construction and operation of the flues andpassages for smoke from the oven, whereby the latter will be evenlyheated at all parts and whereby also the oven may be ventilated, the airsupplied thereto being warmed during its passage through the stove-body.

To these ends it consists in certain im-' provements hereinafter fullydescribed, the novel features being pointed out in the claims at the endof this specification.

In the drawings, Figure 1 isa longitudinal sectional view of a stoveembodying my improvements, taken on the line 1 1 of Fig. 2 Fig. 2, ahorizontal sectional view on the line 2 2 of Fig. 1; Fig. 3, a verticalsectional view taken on the line 3 3 of Fig. 2.

Similar reference-letters in the several figures indicate similar parts.

A indicates the casing or body of the stove or range; 13, the fire-potlocated at one end thereof; C, the oven; 0, the oven-door; D, thevertical smoke-flue located at the back of the stove, having its innerwall formed by the back of the oven. The sheet-flue (indicated by E)extends from the fire-pot over the oven, down at the end thereof, andbeneath it to the plate f, which latter constitutes the rear wall of theash-pit F, as shown in Fig. 1. The front end of the sheet-flue, or thatnearest the fire-pot, is in communication with the rear smoke-flue by adirect-draft aperture G, controlled by the pivoted damper G and adaptedto be opened for affording a direct draft when starting a fire and to beclosed when the oven is to be used for baking, and the lower end of thesheet-flue is open to the smoke-flue at H.

J indicates a partition extending through the upper horizontal portionof the sheet-flue and the vertical portion at the end of the oven anddividing said flue into two passages El E preferably of unequal width,the former, nearer the smoke-flue of the stove, being preferablynarrower than the latter. J indicates a partition arranged in the lowerhorizontal portion of the sheet-flue, 00- operating at one end with thelower end of the partition J and extending forward, so as to overlap thesmoke-flue D when viewed from the front, as shown in Fig. 1.

The relative capacities of the passages E E are such that with a givendraft in the smoke-flue they will draw equally, so that the flames andproducts being divided at the top of the flue will pass from thefire-pot around the oven evenly distributedover the surface of thelatter and heating all sides of it equally. In the top of the oven andat or about the middle portion thereof are a series of perforations, ora single perforation, if desired, leading into the oven and whichconnect with the hollow dividing-partition J, and at or near the'pointwhere said partition connects with the openings above mentioned ispreferably arranged a damper K. At some point in the sheet-flue at theend of the oven or under the oven the hollow partition J is connectedwith the outer air by the air-inlet opening j, the position of whichopening may be varied in different constructions to suit the particularstove to which the invention is applied, the only essential being that asufficient surface of the partition should be exposed to the action ofthe flame and heated products so as to heat the air entering through theinlet j to cause it to rise through said partition with enough velocityto pass into the oven and increase the temperature thereof. The damper Kis shown inclosed in a shallow box K, connected with the hollowpartition J and extending over the air-inlet holes j but may bedispensed with, if desired. At the rear of the oven, adjacent to thesmokeflue D, is an air-outlet d from the oven to said flue, which may becontrolled by a suitable damper d if desired, or this outlet may the volhme admitted through the partition,

be dispens with and the air from. the oven find its ex" through oraround the oven-door 7 whereby the oven will be ventilated thor- Bymeans of the arrangement of the parts described the flame and productswill, when the damper G in the flue O is closed, as in'full lines, Fig.2, pass from the fire-pot around the oven evenly distributed over thesurface of the latter and will cause the .air entering thedividing-partition tobe heated properly before it enters the oven.

I do not claim, broadly, herein a partition arranged in a sheet-fluestove and adapted to divide the sheet-flue into unequal parts, as thisarrangement forms the subject-matter of my pending application, SerialNo. 647,356, filed August 6, 1897.

I claim as my invention 1. In a cooking-stove, the combination of theoven, the fire-pot adjacent thereto, the sheet-flue extending from thefire-pot around the top, end and bottom of the oven, the smoke-flueconnecting with the sheet-flue at the bottom of the oven near the end ofthe sheet-flue, the partition in said sheet-flue extending from near thefire-pot to a point under the oven, said partition being hollow for aportion of its length, having an upper opening into the oven and a loweropening to the external air.

2. In a cooking-stove, the combination of the oven, the fire-potadjacent thereto, the single sheet-flue extending from the fire-potaround the top, end and bottom of the oven, the smoke-flue connectedwith said sheet-flue under the bottom of the oven near the end of saidsheet-flue, a partition in said sheetfiue extending from near thefire-pot to a point opposite the smoke-flue opening under the oven, saidpartition being hollow beginning at a point in the sheet-flue at the endof flue extending from near the fire-pot to a point opposite thesmoke-flue opening under the oven, said partition being hollow beginningat a point inthe sheet-flue at the end of the oven and there having anair-inlet opening and extending to a point above the oven and thereopening into the oven, and an airinlet from the oven into thesmoke-flue.

4. In a cooking-stove, the combination of the oven, the fire-potadjacent thereto, the

single sheet-flue extending from the fire-pot around the top, end andbottom of the oven, the smoke-flue connected with said sheet-flue underthe bottom of the oven, near the end of said sheet-flue, a partition insaid sheetflue extending from near the fire-pot to a point opposite thesmoke-flue opening under the oven, said partition being hollow,beginning at a point in the sheet-flue at the end of the oven and therehaving an air-inlet opening and extending to a point above the oven andthere opening into the oven and an airoutlet from the oven into thesmoke-flue, and dampers controlling said air-inlet into the oven andsaid air-outlet from the oven.
